Abstract
[Object] To provide a formaldehyde detecting sensor capable of constantly monitoring formaldehyde selectively and with high accuracy. [Solving Means] A formaldehyde detecting sensor according to the present invention includes: a reaction portion that contains at least a hydroxylamine salt and reacts with formaldehyde to generate an acid; and a response unit that includes an electrode carrying a carbon material, an electrical resistance value of the carbon material varying depending on the acid generated in the reaction portion, in which the hydroxylamine salt and the carbon material are separated from each other.
